在c＃中获取iso字段的字节数 [英] get iso fields byte numbers in c#

问题描述

我有这个iso8583消息

i have this iso8583 message

0200B2200000001000000000000000800000201234000000010000011072218012345606A5DFGR021ABCDEFGHIJ 1234567890

now我想找出哪个字节数组字段存在。我需要使用c＃。

i知道位图显示消息中存在哪些字段。但我仍然无法获得我需要的输出。

now i want to find out in which byte array field is present.below output i need using c#.
i know bitmap shows which fields are present in message. but i am still not able to get output which i needed.

Field-3 : 201234
Field-4 : 000000010000
Field-7 : 0110722180
Field-11 : 123456
Field-44 : A5DFGR
Field-105 : ABCDEFGHIJ 1234567890

我该怎么做？

how can i do this ?

推荐答案

检查这个代码项目文章： BIM-ISO8583 [ ^ ]

check this codeproject article :BIM-ISO8583[^]

使用正则表达式 [ ^ ]是解决问题的一种方法。



请注意，此代码仅适用于消息中的位置是静态的。

Using Regular Expressions[^] is one way to solve the problem.

Note that this code will only work the positions in the message are static.

Regex rx = new Regex(@"^(?<field1>[0-9A-F]{14})(?<field2>[0-9A-F]{22})(?<field3>[0-9A-F]{6})(?<field4>[0-9A-F]{12})(?<field7>[0-9A-F]{10})(?<field11>[0-9A-F]{6})(?<field12>[0-9A-F]{2})(?<field44>[0-9A-Z]{6})(?<field45>[0-9A-F]{3})(?<field105>[0-9A-Z ]+)

， RegexOptions.IgnoreCase）;

", RegexOptions.IgnoreCase);

（我输入一些虚拟字段来匹配模式）

(I put in some dummy fields to match the pattern)

string input = "0200B2200000001000000000000000800000201234000000010000011072218012345606A5DFGR021ABCDEFGHIJ 1234567890";
Match m = rx.Match(input);
if (m.Success)
{
    string field3 = m.Groups["field3"].Value;
    string field4 = m.Groups["field4"].Value;
    // etc.
}

[更新]

如果字符串是动态的，但您知道所需部件的位置和长度，则可以使用 String.SubString 进行提取。

[Update]
If the string is dynamic, but you know the position and length of the the parts you want, you can use String.SubString to do the extraction.

string input = "0200B2200000001000000000000000800000201234000000010000011072218012345606A5DFGR021ABCDEFGHIJ 1234567890";
int pos3 = 36;
int length3 = 6;
string field3 = input.Substring(pos3, length3);

int pos4 = pos3 + length3;
int length4 = 12;
string field4 = input.Substring(pos4, length4);
// etc.
